"This page isn't available" when I log into Caprine

I got the latest version of the Caprine Flatpak on Fedora Workstation 44. When I logged into Messenger I got this screen. This page isn't available I tried restarting the app and the computer, I tried other networks and I tried logging out from the menu bar option. The menu bar option seems to not be working as well in this case. I hoped that when I press the "return to messenger.com" button it would show the site in Caprine, but it just opens it in the default browser.
